should i put pennies in my fish tank?

i heard that if you put pre-1982 pennies in a bird bath the high copper content will keep the algae at bay. could i throw a couple in my fish tank to do the same or would it kill my fish?

nothing metallic should ever be put into your fish tank. The leeching of the metal into the water is bad for your fish.

If you want to control your algae, do more water changes. The more nutrient export that you do on your water, the less algae will be able to grow. Also, only leave your light on for about 8 hours.
